Complex packing motifs templated by a pseudo-spherical guest: the structure of β-cyclodextrin–adamantaneinclusion compounds

“…[1][2][3][4] Attempts to correlate the type of packing observed with guest molecule properties have been somewhat successful for a-and g-cyclodextrins but not with the more commonly employed b-cyclodextrin (BCd) host. 2 Our laboratory had been actively studying the guest dynamics in cyclodextrin inclusion compounds for a number of years.…”

Determination of the Absolute Configuration of Aegelinol by Crystallization of Its Inclusion Complex with β-Cyclodextrin

“…Packing diagrams are available in different reports on β-cyclodextrin complexes; the reader is referred to these works for both diagrams and discussion of the different structural properties for these packing arrangements [35][36][37]. The CD host molecules are associated through hydrogen bonding between secondary hydroxyl groups as dimers, packing in the previously observed (Im) packing arrangement [35][36][37]. The fact that this arrangement is common to these complexes of β-CD is important for two reasons:…”

“…Crystalline complexes of hydrogen-bonded β-cyclodextrin dimers complexed with organic guest molecules have been found previously to adopt one of four crystal packing motifs: a channel motif (Ch), a checker board motif (CB), an intermediate motif (Im), and, most recently, a tetrad motif (Tt). Packing diagrams are available in different reports on β-cyclodextrin complexes; the reader is referred to these works for both diagrams and discussion of the different structural properties for these packing arrangements [35][36][37]. The CD host molecules are associated through hydrogen bonding between secondary hydroxyl groups as dimers, packing in the previously observed (Im) packing arrangement [35][36][37].…”
